This is hopefully the thread to end all of my RX series questions post and responding in other threads

How efficient are you guys able to run these cards on what coins, and is this a wall or software sensor measurement? And of course what variation of the 470 and 480 do you have and with which memory if you know it?

6 MSI RX 480 Gaming X 8GB rig https://www.amazon.com/MSI-GAMING-RX-480-8G/dp/B01K1JTT8S/ref=sr_1_1?ie=UTF8&qid=1486433923&sr=8-1&keywords=rx+480+msi
~1100w/ETH, ~930w/XMR at wall - undervolted for ETH/XMR and overclocked for ETH
Specifically testing XMR, GPU-Z shows that these MSI cards pull ~120w per card while mining XMR. ETH was the full 150w of the GPU
These can be overclocked slightly for ETH, but not XMR.

6 XFX RX 480 8GB RS rig http://www.bestbuy.com/site/xfx-hard-swap-edition-amd-radeon-rx-480-rs-8-gb-gddr5-pci-express-3-0-graphics-card-with-white-led-backlight/5550001.p?skuId=5550001
~1000w/ETH, ~850/XMR at wall - only undervolted for both XMR/ETH
Specifically tested with XMR, GPU-Z shows these XFX cards pull ~80w per card while mining XMR. ETH was full 150w of the GPU.
I have not successfully overclocked this at all. I can't change anything because it will freeze.

Really nice on the details, very much appreciated. What's the hash rate difference on the two different sets when mining XMR?

I'm going to assume 29-31 MH/s on ETH

Got 6x470 (all sapphire Nitro 4GB, different mem chips though : 3 samsung, 2 elpida, 1 hynix) mining xmr @ ~ 4400 H/s. About 640W at the wall for the whole system so that's around 100W/card. No big difference between them in terms of hashing except for the hynix which is a bit lower (but it's the gpu on display).

Best choice regarding H/W and H/$ would be currently RX470 4G. However if you can find a 480 4GB at the same price, go for the 480

what core/mem settings r u using for the RX 470 rig? 1150/2000? 640W ist very low for the whole rig. the measurement is from the wall?

Mesurement is from the wall. Got a 1000W gold PSU@220V so that should be around 90% efficiency.

For now core is at 1200 and mem between 1950 and 2100 depending on the GPU. The undervolt is light (between 0,95V and 0,975V).
Will try to decrease core & undervolt to see if it's worth it. But since my rig is stable i got a bit lazy <_<
The big difference in Power draw came from using -a 2 setting in Claymore.
